Police searching a computer put a 'black box' between the computer & drive, to read, but not write, alter or erase data. Answered
How do you build such a device?
I wish to add a second hard drive to my ThinkPad A22m laptop, for a protected archive of books, websites, programs, and pictures.
I want to have a switch so that at intrevals I can add files, but if a virus got loose in the computer it could not get into the archives.
